Smallest particle of an element that participates in chemical reactions
Explanation
An atom is the smallest particle of an element that participates in chemical reactions. It is the fundamental building block of matter and retains the chemical properties of the element it belongs to. Atoms combine with other atoms to form molecules and compounds, allowing for the formation of various substances and the occurrence of chemical reactions. The plural form of atom is atoms, referring to multiple individual particles of an element.Rate this question:

TRUE OR FALSE:IONIC COMPOUND DISSOCIATE WHEN THEY DISSOLVE IN WATER
Explanation
Ionic compounds dissociate when they dissolve in water because water molecules surround the ions and pull them apart, breaking the ionic bonds. This process is known as hydration. The positive ions (cations) are attracted to the negative oxygen atoms in water, while the negative ions (anions) are attracted to the positive hydrogen atoms in water. As a result, the ions become surrounded by water molecules and are able to move freely in the solution, leading to the dissociation of the ionic compound.Rate this question:

ATOMS THAT CARRIES NO CHARGE
Explanation
Neutrons are atoms that carry no charge. They are subatomic particles found in the nucleus of an atom along with protons. While protons have a positive charge and electrons have a negative charge, neutrons have no charge at all. They are crucial for stabilizing the nucleus and determining the isotope of an element. Neutrons play a vital role in nuclear reactions and are also used in various scientific and medical applications, such as in nuclear power plants and cancer treatment.Rate this question:

ATOM THAT CARRIES A NEGETIVE CHARGE
Explanation
Electrons are the atoms that carry a negative charge. They are subatomic particles that orbit around the nucleus of an atom. Electrons are negatively charged because they have a fundamental property called charge, which can be either positive or negative. In an atom, the number of electrons is equal to the number of protons in order to maintain overall electrical neutrality. When an atom gains or loses electrons, it becomes an ion with a positive or negative charge, respectively. Therefore, electrons are the correct answer as they are the particles responsible for carrying a negative charge.Rate this question:

WITHIN ENZYME REACTION IDENTIFY THIS FUNCTION:CHEMICAL THAT SPEEDS REACTION BUT IS NOT PART OF THE REACTION
Explanation
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction itself. It works by providing an alternative pathway for the reaction to occur, lowering the activation energy required for the reaction to take place. In the context of an enzyme reaction, a catalyst can speed up the reaction by facilitating the formation of the enzyme-substrate complex, but it is not directly involved in the reaction itself. Therefore, the correct answer is catalyst.Rate this question:

IN ORDER FOR NA+ TO BE CREATED. SHOULD ELECTRONS LOOSE AN ATOM
Explanation
The given answer suggests that in order for Na+ (sodium ion) to be created, electrons need to be lost by an atom. This is because sodium has one valence electron in its outermost energy level, and in order to achieve a stable electron configuration, it tends to lose this electron and form a positive ion with a +1 charge. This process of losing electrons is known as ionization. Therefore, the statement "LOSE ATOM, YES" correctly explains the process of creating Na+ ions.Rate this question:

TRUE OR FALSE:pHOSpHOLIPIDS ARE NOT SOLUBLE IN WATER
Correct Answer
FALSEExplanation
Phospholipids are amphipathic molecules, meaning they have both hydrophilic (water-loving) and hydrophobic (water-fearing) regions. The hydrophilic head of a phospholipid molecule is soluble in water, while the hydrophobic tails are not. This unique property allows phospholipids to form the lipid bilayer of cell membranes, with the hydrophilic heads facing the aqueous environment and the hydrophobic tails facing inward, away from water. Therefore, phospholipids are indeed soluble in water to some extent, making the given answer "FALSE" correct.Rate this question:
